srnme MATTRESS.

Application filed December 14, 1923, Serial No. 680,639.

To all whom it may concern:

Be it known that I, HARRY M. YOUNG, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented a certain new and useful Improvement in Spring Mattresses, of which the following is a specification, reference being had to the accompanying, drawing, forming a art thereof. I

'lfhis invention relates to a certain new and useful improvement in spring-mattresses of the type that includes a link, woven, or knitted wire-fabric or other so-called yielding or resilientbody and has for its chief ob ect the provision of a spring-mattress of the type stated comprising a supportingframe or structure so constructed that the yielding properties or resiliency-the stretch or tightness of the woven, link, or knitted fabric or other resilient or yielding body'of the mattress may be conveniently adjusted or regulated to increase or decrease the tension or stiffness of'the body to meet different individual requirements.

lVith the above and other objects in view, my present invention resides in the novel features of form, construction, arrangement, and combination of parts hereinafter de scribed and pointed out in the claims.

In the accompanying drawing,

Figure 1 is a broken plan viewof a springmattress embodying my invention;

Figure 2 is a side elevational view ofthe mattress; and

Figures 3 and 4 are, respectively, perspea tive and front elevational views of one of the body-adjusting brackets of the frame of the mattress.

Referring now more in detail and by reference characters to the drawin", which illustrates a preferred ()FflbOCllll'lBDt of my invention, A designates the so-called yielding or resilient body of the mattress, which is in the form preferably of any suitable woven or knitted wire fabric.

Supporting the body A, is a frame Comprising head-rails 1, 1, preferably of angleiron form, to which heads 1, 1, the body is suitably attached at its longitudinal ends preferably through the employment of a- ,plurality of coil-springs or, the like 2, as best seen in Figures 1 and 2 and as will be well understood, the lateral margins of the s y a bei P f a ly bounded 1 finis ed Die by suitable so-called sag-rails 3, 3, similarly attached at their ends to the frameheads 1, 1. 1

Riveted or otherwise rigidly fixed to, and depending from, the opposite ends of framehead 1, are preferably rigid corner-brackets 4:, 4, of any suitableor standard form and construction; and riveted or otherwise rigidly fixed to, and depending from, the opposite ends of the other frame-head 1, are the upper members 5, 5, of cornerbraclrets B of novel form and construction, now to be described.

The member 5 of each bracket B is sub stantially in the form of an angle and comprises a main wall flat at its upper portion, as at 6, to fitsmoothly against and for riveted engagement with the inner face of the depending limb of the head-rail 1, and preferablybodily curved or arcuated, as at 7, from its fiat portion 6to its lower end, as shown. Integral with said wall at its opposite side edges, are lateral strengthening flanges 8, 8', the flange 8' extending upwardly slightly above the upper margin of fiatwall-portion 6-and said wall and its flange 8 being provided with a ledge 9 having its upper face disposed in the plane of the upper margin of the wall-portion 6 and its other flange 8, so that the bracket-memher 5 may snugly seat in riveted or fixed position upon the end margin of the headrail 1, as shown. Projecting rearwardly from the lower margin of and approximately at right angles to said main wall, is a socalled plate or bottom wall 10 preferably rounded at its free edge; and formed upon the bracket-member 5 and projecting forwardly from, and at the lower margin of, its said main wall, is a pair of suitably spaced pivot-lugs or ears 11, 1.1. Integral with said main and bottom walls, is pref erably a )late-strength n1ing web if), best seen in Figure 3.

Cooperating with its member 5 and forming the complementing part of the bracket 13, is an oppositely disposed angle member 13 comprising a mainwall 1 1- formed upon its oneside and lower margins with a substantially continuous lateral strengthening flange 1 5 and upon its other side margin with a lateral strengthening flange 16, the

fianges 15 and 16 at the inner lower corner f he m mber 13 me i ets re r y presented socket 17 also, in turn, integral at its closed end with the wall 14; Projecting rearwardly from the upper margin of and approximately at right angles to sidewall 14 i, is a second so-ealled plate or upper wall 18 similarly rounded at its free edge and in.

opposing companionship to the bottom wall 10 of the bracket member 5; and projecting forwardly from and at the upper margin of said wall 14-, is likewise apairof suitably located pivot-lugs or cars 19, 19. Disposed lengthwise through and having engagement with the pairs of ears or lugs 11, 11, and 19, 19, for pivotally or hingedly securing or fastening the angle-members 5 and-13 together, is a pintle '20.

Seated for threaded-'movement in the bottom-wall 10 of bracket-member and engaging at its lower end upon the opposing upper wall-'18 of the bracket-member 13, is a bracketadjustingscrew or the'like 21.

Completing the body supporting structure or frame and seated atone end inthe sockets 17 of the brackets B and at' the other end in companion-sockets 22 of the brackets 4, are frame side-bars 23;

In use, as will be well understood, the complete mattress is suitably disposed upon a bed-frame, not shown, and normally, as illustrated in Figure 2, the adjusting screw 21 is in such seated oradjusted condition as to somewhat arcuately orhi'ngedly space the wall-members 10 and 1 8 of the bracket B, when; aswill be obvious, the body A will be stretched or distended to a certain degree of tension or stiffness Should, however, it be desired to increase the stiffness or tension and thereby further reduce-theresiliency or yielding condition of'tlie body A, then the screw 21 may be so further manipulated as to correspondingly further hingedly" space the bracket-walls l0 and 18, such movement of'the bracket-member shifting the headrail 1 away from the fiXedhead-rail 1 and consequently stretching the fabric body A and its fastening springs 2 and thereby tightening or increasing the tension of the same upon the supporting structure. Conversely, should it be desired to reduce the stiffness and increase the resiliency or yielding properties of the body A,.then the screw may be so reversely manipulated as to correspondingly permit the bracket-wall 10 to hingedly move toward the bracket-wall 18, such latter movement of the bracketmember 5 shifting the head-rail l" toward the fixed head-rail 1 and reducing the pull or tension upon the body- A; and its fastening springs 2 and thereby loosening the same upon the supporting structure.

My new spring mattress is simple, compact, and relatively inexpensire in form. and construction, is convenient, positive, and durable in adjustment, readily accommodates the requirements for comport' of different individuals and thereby enables the manufacturer to increase his production with a standardization of product, permits ready adjustment of either longitudinal side of the mattress independentlyof the other, and is exceedingly efiicient inv-the performance of its intended functions.

I am aware that changes in the form, construct-ion, arrangement, and combination of the several parts of my new spring-mattress may be made and substituted for those herein shown and described without departing from the nature and principle ofmy invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:
